There are strong feeling on both sides of whether or not to replace trans fluid. Some have solved tranny issues by changing fluid, some think the change was the reason the tranny failed sometime later.

I am in the camp that changes the fluid for no other reason than petroleum products break done over time. I have changed fluid every 50,000 miles and have around 108,000 miles on original transmission--and I drive hard.

It is good advice to change all fluids if a vehicle has has spent a lot of time sitting but even with the camp I am in I wouldn't change your the transmission fluid unless it is acting up now and in a manner that others say has been corrected by changing the fluid.

Great to have the history!
